Summary of results
======================

It is possible to represent the junction of a crack for a crack already resulting from a junction. The two junctions can be close and there is no need to refine the mesh in the area that contains the 2 junctions.

The approach was validated in :math:`\mathrm{2D}` for C_ PLAN and D_ PLAN models and for elements of type QUAD4 and TRIA3. The approach was also validated in :math:`\mathrm{3D}` for elements HEXA8 and TETRA4 with and without contact.
